Monitoring System Of The Transformer's Running State Based On The Acoustic Wave

As borrowing ideas from the experienced workers'sense organ experiences, the relationship of the transformer's running states and its acoustic wave character have been researched. A new method of monitoring the transformer's sate has been put forward based on the running acoustic wave. So we develop a system to monitoring the state of transformer. This system uses the chip microcomputer as the chief parts of data acquisition and its hardware circuit has been designed. Using the two parts the system gather the acoustic waves of the transformer and using the Dynamic Time Warping, the Hidden Markov Model and the fuzzy diagnosis to analyze the acoustic wave data. From the experiment of acoustic wave collect, we approve the hardware is reasonable and the analyze method is proper.
